1 Claim. (01. 196-93) '7 I This invention relates to improvements in the system and apparatus particularly designed for the distillation of oil, and has as its object an improved still for the distillation process together 5 with improved means whereby the distillation and the refinement of the oil may be carried out without resort to chemicals.

A still further object of the invention is to provide a system and apparatus for carrying out the system whereby the distillation of the oil is carried out with extreme simplicity and with such efiiciency that upon delivery to the receiving tank the product, in the present instance, gasoline is ready for immediate consumption.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the acompanying drawings wherein:

Figure 1 is a diagrammatic view of the apparatus.

Figure 2 is an enlarged sectional view taken through the still.

Figure 3 is a sectional view taken substantially on the line 33 of Figure 2.

Figure 4 is an enlarged sectional view taken through the cooler and illustrating certain details in construction hereinafter more fully referred to.

Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 4, and

Figure 6 is a sectional view taken through one of the spray pipes.

Referring to the drawings by reference numerals it will be seen that the still indicated generally by the reference numeral Ill comprises a base II upon which is mounted a drum I2 provided in one end with a manhole I3. At the end thereof opposite to the manhole I3 the drum I2 has rising therefrom a dome M.

The base II is formed to provide at opposite sides thereof feeding chambers I5 into which extends blast nozzles I6. It will of course be understood that a suitable stack or the like will be provided for the chambers I5 for carrying off 45 the waste products of combustion.

The oil to be distilled is fed from a suitable source of supply to the drum I2 of the still by a supply pipe I! suitably connected to an inlet nipple I8 provided in the top of the drum I2 at the end thereof remote from the dome M.

In accordance with the present invention steam from a suitable source of sup-ply is fed by a pipe I9 to the still, and a portion of the pipe I9 extends through a suitable opening in the head of the drum l2 remote to the manhole I3 and exteriorly of the drum the steam supply pipe is provided with a suitable valve 20. At its inner end the pipe I9 terminates midway between the ends of the drum I2 and is connected to a vertical pipe 2| which latter is connected by a T 22 to oppositely extending perforated spray pipes 23. Obviously steam entering through the pipe I9 will discharge into the oil below the level of the oil through the perforations in the pipes 23. g

The vapors resulting from the distilling of the oil will rise to the dome I4 and be carried off by a pipe 24 that is connected at one end with the top of the dome I 4 as shown in Figure 2. The pipe 24 extends for any suitable distance from the still and is provided to discharge into a suitably located receiving tank 25. The tank 25 is provided adjacent its bottom with a valve drain 26 whereby the sediment is drained from the tank, and adjacent its upper end the tank 25 is provided with a valve equipped drain 2'! through which the gasoline in its final state of purification is drawn either for immediate use or for further cracking thereof or for any other purpose found desirable.

For cooling purposes there is disposed about an intermediate portion of the pipe 24 a casing 28 provided at the rear end with an intake connected to a suitable water supply conduit 30, provided with a valve 3|, and at the front or opposite end with a water outlet 29. Thus a continuous circulation of water through the chamber formed by the casing 28 may be maintained for cooling the distilled oil in its passage through the pipe 24 from the still to the receiving tank 25.

An important feature of the present invention resides in providing in the pipe 24 intermediate the ends of the casing 28 a T or other suitable fitting 32 and associated with this fitting a spray device whereby cold water is injected in spray form into the distilled oil to insure a thorough separation of the sulphur and other particles thus completing the purification of the oil. Through the medium of the above referred to spray device this final purification step is accomplished without resort to chemicals as is now generally required. The said'spray device comprises a pair of oppositely extending perforated spray tubes or nozzles 33 connected by a T or other suitable fitting 34 with a nipple 35 that in turn is threaded into a plug 36. The plug 36 is threaded into the stem portion of the T 32 and also threaded into the plug 36 is one end of a water supply pipe 31. Thus water from a suitable cource of supply passes through the pipe 31, the nipple 36 and the T 34 to discharge in spray form from the perforated tubes 33 and into the vapors passing through the pipe 24. As shown in Figure 1 the pipe 31 is provided with a suitable control valve 38.

It will be seen that vapors from the still will flow through the pipe 24 into the coupling 32 and then from this coupling, the vapors will enter the rear section of the pipe 24 and as the vapors are passing from the front section of the pipe 24, through the coupling 32 and into the front end of the rear section of the pipe 24, they will be subjected to the cold water spray from the perforated pipes 33 and this cold Water spray acting on the hot vapors will cause the separation of the sulphur therefrom as well as the condensation of the vapors so that the condensation will flow through the rear section of the pipe 24 into the tank 25. I have found that these vapors must be held at a certain temperature when being acted upon by the cold water spray in order to cause the separation of the sulphur. This is done by placing the spray de vice in an intermediate part of that portion of the pipe 24 which passes through the jacket 28 so that the water entering the jacket through the pipe 30 will be heated by the vapors and condensate in the conduit 24 as the water flows towards the outlet 29 so that this heated water will keep the vapors at the proper temperature to cause the cold water spray from the pipes 33 to separate the sulphur from the vapors. The separated sulphur will drop into the bottom of the tank 25 so that the oil or condensation drained from the tank 25 through the pipe 21 will be free from sulphur.

Having thus described my invention, what I claim as new is:

An oil distilling apparatus comprising a tank for receiving the oil to be distilled, means for heating the oil within the tank, means for injecting steam into the oil within the tank, a dome connected with the top of the tank, a substantially horizontal pipe of substantially the same diameter throughout connected with the top of the dome for leading the vapors from the tank, an elongated jacket surrounding part of the pipe and having its front end spaced from the tank, means for introducing cold water into the rear end of the jacket, the front end of the jacket having an outlet for the Water, a receiving tank located below the discharge end of the pipe and into which the pipe discharges, upper and lower drain pipes connected with the last mentioned tank, a perforated spray pipe located in an intermediate part of that portion of the first mentioned pipe which passes through the jacket, said spray pipe extending longitudinally of the first mentioned pipe and spaced from the internal Walls thereof, and means for connecting the spray pipe with a supply of cold Water.
